Description

  

  Verfahren zur     Herstellung;    eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  auf den     Farbstoff    aus dianotierter     6-Nitro-2-          aminophenol-4-sulfosäiire    und     ss-Naphtol    die  Chromverbindung des Farbstoffes aus diano  tierter     1-Ainirio-2-oxyriaphthalin-4-sulfosäure          und        a-Naphthol    einwirken lässt.  



  Das neue Produkt stellt ein schwärzliches  Pulver dar, löst sich in Wasser und in  10     0lo        iger    Natronlauge mit     schwärzlichblauer,     in konzentrierter Schwefelsäure mit     grünlich-          blauer    Farbe und färbt Wolle und Seide in       schwärzlich    marineblauen Tönen von vorzüg  lichen Echtheitseigenschaften.

      <I>Beispiel:</I>  10 Teile der Chromverbindung des Farb  stoffes aus dianotierter     1-Ainino-2-oxynaph-          thalin-4-sulfosäure    und     a-Naphthol    werden in  250 Teilen Wasser kochend gelöst, 2 Teile  des     Farbstoffes    aus dianotierter     6-Nitro-2-          aminopheriol-4-sulfosäure    und     P-Naphthol    hin  zugelöst, das Lösungsgemisch mit Essigsäure  schwach angesäuert und längere Geit rück-         fliessend    gekocht. Durch teilweises Eindamp  fen und     Aussalzen    kann der neue     Farbstoff     gewonnen werden.



  Method of manufacture; of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the chromium compound of the dye from dianotated 1-ainirio-2-oxyriaphthalene-4 is added to the dye from dianotated 6-nitro-2-aminophenol-4-sulfosäiire and ß-naphthol -sulfonic acid and a-naphthol to act.



  The new product is a blackish powder, dissolves in water and in 10 0lo sodium hydroxide solution with blackish blue, in concentrated sulfuric acid with greenish blue color and dyes wool and silk in blackish navy blue tones with excellent fastness properties.

      <I> Example: </I> 10 parts of the chromium compound of the dye from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and α-naphthol are dissolved in 250 parts of boiling water, 2 parts of the dye from dianotized 6 -Nitro-2-aminopheriol-4-sulfonic acid and P-naphthol dissolved, the mixed solution was slightly acidified with acetic acid and boiled under reflux for a longer period of time. The new dye can be obtained by partial evaporation and salting out.
